- Abstract
Background Rapid advances in multiple myeloma (MM) therapy have led to improved survival, yet the impact of novel agents on the risk of invasive fungal infection (IFI) is largely unknown. We aim to describe the epidemiology of IFIs in MM patients in the current era of chemotherapy. Methods We performed a retrospective chart review of MM patients at Mount Sinai Hospital in New York, NY who entered care between December 2009 and October 2016 and had proven or probable IFI between January 2011 and October 2017. Probable and proven IFIs were defined by revised EORTC/MSG criteria. Descriptive statistics are reported as median (range). We evaluated factors associated with mortality by univariate analysis using Fisher's exact and Mann–Whitney U tests. Results 2,960 MM patients entered care during the study period. We identified 30 episodes of IFI among 29 patients. Median age was 59 (42–80) years and 21 (70%) were men. IFI occurred at a median of 3.7 (0.3–18) years from MM diagnosis. At the time of IFI diagnosis, patients had received a median of 4 (1–12) lines of chemotherapy, 18 (60%) had undergone autologous stem cell transplant (ASCT), and 21 (70%) had progressive disease status. Agents received immediately prior to IFI were immunomodulators (n = 14), proteasome inhibitors (n = 14), conventional chemotherapy (n = 11), monoclonal antibodies (n = 6), checkpoint inhibitors (n = 3) and other (n = 3). Twenty-two (73%) patients received corticosteroids in the prior 30 days. Neutropenia and lymphopenia were present in 12 (40%) and 13 (43%) patients, respectively. There were 9 proven and 21 probable IFIs: invasive aspergillosis (n = 19), candidemia (n = 5), cryptococcosis (n = 3), talaromycosis (n = 1), mucormycosis (n = 1) and other (n = 2). Bacterial and viral respiratory co-infections occurred in 7 and 4 patients, respectively. Eight (27%) patients required ICU admission and 9 (30%) died within 30 days of IFI diagnosis. In univariate analysis, number of lines of chemotherapy (P = 0.05), progressive disease status (P = 0.03), and prior ASCT (P = 0.004) were associated with 30-day mortality. Conclusion IFIs are uncommon in MM patients receiving newer agents but are associated with significant morbidity and mortality. Further study is needed to identify high-risk subgroups that may benefit from antifungal prophylaxis or increased surveillance. Disclosures All authors: No reported disclosures.
